' ELECTRICAL FEELER roa LOOMS.

Application filed October: 18, 1926.5 Serial No. 142,340. A:

- ed in order. toprevent mispicks.

o-Briefly,thejinvention has reference to a. structure of this kind whichis ofan electricahnature and includes abase plate to be attached to astationary part of the loom, there'being .a longitudinally movablespring pressed feeler mounted upon this base and provided with acorrugated tip for cooperation with the filling on the bobbin. A feelerof this typehas now become well known as a the sidelswipe embodiment.

' Our principal aim isto generally improve upon structures of this.class by providing one of comparative simplicity and durability whereinthe parts are associated in a novel manner to produce a more practicaland etficicntdevice,and one which will accurately detect the conditionof the filling at all times and will positivelycome into play forstopping the loom before the filling is exhausted.

Other features and advantages of the invention will become apparent fromthe following description and drawings.

In the drawings Figure v1 is a top plan View of the attachment per se,showing the parts in one position.

Figure 2 is a View like Figure 1, showing the parts in another position.

Figure 3 is a cross section taken approximately upon the plane of theline 33' of Figure 1.. I

' Figure at is a similar cross section showing the latch mechanism, and

Figure 5 is a perspective view of the tip.

Referring to the drawings in detail it will be seen that the referencecharacter 1 desighates the base plate which is of general oblongeonfiguration, the same being provided on one longitudinal edge with anelongated slot 2, serving to permit the device to be attached to thestock parts of the existing loom without requiring alterations. On theopposite side, the plate is formed with a PG? culiarly shaped guide slot3, which serves in a manner to be later discussed.

At one end of the plate is a guide loop 4 through which the reduced endof the feeler arm 5 slides. It will be noted however that the guide issomewhat elongated to permit the aforesaid side swipe action.Thecentrail portion of the arm is widened somewhat as at 6 and providedwith a beveled shoulder.

A pivoted latch 'I having an angularly directed detent or finger is seenplainly inFigure 4:. Normally, this finger restsslidably upon tlie wide,portion ot the feeler. While considering this part attention is directedto a bracket 8 which is mounted on the base plate and constitutespivotal mounting for the latch, there being an upstanding lug 9 here,and a coil springlO being interposed between. the lug and the butt endof the latch. This holds the 'detent of the latch in contact with thefeeler in an obvious manner. It will be noted that the bracket includesan elongatedbase 11 which is adjustably mounted on the main baseplate 1.This permits accurate adjustment of the parts to render them moresensitive.

Fastened to the opposite end of thebase plate is an arched part 12constituting a mounting for a pivot joint 13, the jointbeing formed witha central bore. The feeleris providedadjacent these parts with a reducedcylindrical extension lt'which extends slidably through the bore, and itwillbe noted that a coil spring15 surrounds this portion 1a, andv bearsagainst the enlarged central body portion. It isplain to be seen that.this spring. serves to holdithe corrugated tip 16 in contact with thefilling on the bobbin.

Attention is now directed to an upstanding ear 17 carrying an adjustablecontact screw 18 with which a suitable electrical connection 19 isassociated. Also, a bridge piece 20 is carried by the central portion ofthe feeler and constitutes a relatively movable electrical contact forcooperation with the adjacent end of the contact screw 18. Furthermore,the feeler arm is provided on its under side and at its center with astud which is movable in the slot 3 and is adapttant part. Normally asthe teeler arm reciprocates back andforth, resisted and attected by theaction of the coil spring, the depending detent on the latch simplyslides or rides on the relatively wide central portion of the arm.However, after the material on the bobbin has substantially run out andthe tip comes into engagement with the core of the bobbin and side swipeact-ion takes place the arm moves over, bringing the cross piece 20 intoelectrical engagement with the adjustable screw 18, thus stopping themachine. At this time, the detent 011 the latch 7 engages the lowercentral portion-0f the longitudinal edge of the feeler arm and holds thearm over, with the contacts thusengaged.

Of course when the new bobbin is placed in the shuttle, the thickness ofthe material wrapped thereon forces the teeler arm down against thetensionof the spring 15 and in so doing, the bevelled shoulder on thewidened portion of the arm rides underneath the detent and lifts thelatch up. The adjustability of the latch is desirable in that differenttextures of material are used on the bobbin. Obviously, where silk isemployed, adjustability of the latch becomes necessary to regulate thesensitiveness of operation.

Undoubtedly, by consideringthe foregoing description in association withthe drawings, persons familiar with devices of this class will be ableto obtain a clear understanding of the same. For this reason, a morelengthy description is thought unnecessary.

Minor changes coming within the field of invention claimed may beresorted to if desired.

Having thus described the invention, what we claim as new and deslre tosecure by Letters Patent 1s 1 A loom attachment of the class describedcomprising a base plate having a transversely elongated guide at oneend, an arched bracket at the opposite end, a pivot member mounted forswinging movement in said arched bracket, a longitudinally and laterallymovable feeler' arm having one end portion extending through said guideand having the opposite end portion connected with said pivot member, anadjustable contact member screw carried by said base plate, acooperating contact carried by the intermediate portion of the feelerarm, spring means associated with said feeler arm, together with aspring pressed pivotally mounted latch cooperable with the intermediateportion of the teeler arm, said latch being adjustably mounted on thebase Plate.

2. In a loom attachment of the class described, a base plate providedwith a transversely elongated guide at one end, an arched bracket at theopposite end, a pivot member mounted for swinging movement in saidarched bracket, a longitudinally and lat erally movable feeler armhaving one end portion extending through said guide and having theopposite end port-ion connected with said pivot member, said feeler armembodying a comparatively Wide central portion provided With a bevelledshoulder, spring means associated with said teeler arm, an adjustablecontact screw'mounted on said base plate, a cross piece carried by saidfeeler arm and cooperable with said screw, an adj ustably mounted springpressed latch mounted on said base plate, said latch having a dependingdetent cooperable with said feeler arm for maintaining said cross piecein engagement with said contact screw.

In testimony whereof we affix our signatures.
